Spline ulanish kalkulyatori — ISO 4156
Involute spline geometry per ISO 4156 (metric module, side fit). Enter module, number of teeth, pressure angle, engagement length, and torque for a simplified bearing-stress and torque-capacity estimate — a common design practice, not part of ISO 4156.

Pitch Diameter
Simplified Spline Bearing-Stress Estimate
where h = effective tooth height (approx 0.9m), z = teeth, L = engagement length, K = load distribution factor, Dp = pitch diameter.
Load distribution: K=0.75 fixed, K=0.5 sliding under load. This calculator uses K=0.75.
Note: ISO 4156 defines involute spline geometry, tolerances, fits and inspection — it does not specify a load-capacity method. The bearing-stress, torque-capacity and safety-factor results above are a simplified engineering estimate (uniform load sharing, effective tooth height h ≈ 0.9m, empirical factor K) commonly used in design practice; they do not constitute ISO 4156 compliance. Verify critical designs with detailed analysis.
